The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. A number of undesired side effects sometimes occur during chemotherapy. There has been a vast growth in the field of herbal medicine and these drugs popularly are increasing both in developing and developed countries because of their natural origin, more therapeutic effect and less side effects. Since ancient cultures, tribal people methodically collected information on herbs and developed well-defined herbal drugs for the treatment of many diseases. Mostly, cancer patients are gaining benefit from treatment with herbal medicine. In the present study the anti cancer activity of the existing drug (Erlotinib) and natural compound Curcumin
